I had created flat cardstock invitations and coordinating envelope designs for my daughter's baby shower. These envelopes are a great quality paper and went through my printer smoothly. They looked professionally done.
Since I couldn't find envelopes that are closer to 5x7 which is what I really needed these worked fine. I really wish we all hadn't become so lazy to not be able to lick/sponge a bit of glue. That little sticker cover is just another little landfill filler.
I use the envelopes to mail greeting cards for personal use and for a club where I create cards for members birthdays congratulations get-well sympathy. The size is perfect for the cards I create and I like the no-lick sealing.
